Question 1

What does a side-return or rear extension cost on a 1930s semi in Wembley (HA0 or HA9)?

Accepted Answer

On a typical interwar semi in HA0 or HA9, a single-storey rear or combined side-return extension runs between £42,000 and £78,000 at mid-range specification — groundworks, structural steelwork, roof glazing or lantern, and a new kitchen or dining layout inside. Exact figures shift with span, ground conditions, and finish level. Most standard rear extensions on Wembley semis fall under permitted development limits, making a lawful development certificate the usual route rather than a full planning application. PrimeCraft itemises every cost separately — labour and materials on distinct lines — and delivers the breakdown on the same day as the visit.

Question 2

Are the hipped roofs on HA9 semis near Wembley Central suited to loft conversions?

Accepted Answer

Generally yes. Interwar semis across HA9 and HA0 were built with hipped roofs at pitches that suit a hip-to-gable conversion well — pairing that gable with a rear dormer produces a proper double bedroom and en-suite rather than a cramped space under the slope. PrimeCraft checks ridge height, rafter condition, and party-wall position at survey before advising on what the roof can deliver. Most conversions in this stock proceed under permitted development via a lawful development certificate; properties subject to an Article 4 direction or in a locally designated area need a full planning application, which we flag at quote stage.

Question 3

Can PrimeCraft work on leasehold flats in the newer Wembley apartment blocks around the stadium?

Accepted Answer

Yes — the purpose-built blocks around Olympic Way and the wider stadium quarter fall within the area PrimeCraft covers. Leasehold flats carry an extra consent layer: the managing agent or freeholder typically requires a licence to alter, method statements, and insurance evidence before structural work or a new wet room can proceed. PrimeCraft prepares that documentation as part of the project and runs the approval process alongside pre-build preparation, so construction starts promptly once consent is issued. Boiler and heating work across Wembley is handled through a Gas Safe registered partner.
